Phoenix Contact 2320173 Redundancy Module – QUINT-ORING/24DC/2X10/1X20

The Phoenix Contact QUINT-ORING/24DC/2X10/1X20 (2320173) is a high-performance redundancy module designed to deliver uninterrupted 24 V DC power in critical industrial applications. With Auto Current Balancing (ACB) technology, it ensures symmetrical load distribution between parallel power supplies, significantly extending power supply service life and maximizing system availability.

Equipped with a protective conformal coating, this QUINT ORING module is optimized for harsh environments. It supports 20 A output current or dual 10 A inputs, advanced monitoring via relay signaling, and features SFB Technology for high-speed circuit breaker tripping. Ideal for redundant architectures in automation, energy, and control systems.
